Control of Cracking in Precast, Prestressed Concrete Panels for Bridge Decks

The objective of this study was to reduce the collinear cracking that can occur during fabrication and transportation of precast, prestressed concrete panels for bridge decks. It was found that, lowering initial prestress from 189 to 169 ksi (1300 to 1165 MPa) and using a lump-sum prestress loss of...
